(optional)

Helps extend the time that the yeast stays cool in transit. Cool temperatures help keep the viability of the yeast higher which in turns leads to faster fermentation start times and better beer. The Insulated shipper helps the ice last much longer, however neither option will ensure your yeast stays cool the entire trip.

A classic pilsner strain from the Czech Republics premier pilsner producer. Relatively dry with a malty finish, this yeast is best suited for European pilsner production.

Optimum Fermentation Temp: 50–55°F

Attenuation: 72–77%

Flocculation: Medium to High

Alcohol Tolerance: Medium (5–10%)

Cell Count: 100+ Billion

Brewing Tip: We Recommend you make a yeast starter for all lagers. Because of the cold environment you will need about 4 times as much yeast to successfully ferment a lager. If you don't have a yeast starter pitch 2-4 vials at 60-70°F and cool to 48-52°F within 12-18 hours. To ferment lagers like the German's and Czech's make an active starter of 2000ml per 5 gallons. Pitch at 45-48°F and let it naturally rise to 48-52°F. Hold your fermentation at 48-52°F for 4-6 weeks in the primary. A diacetyl rest is recommended after the last week of fermentation. Raise to 55-58F for 3-5days and crash to 40F. It is normal if lager fermentation takes 3-4 days to show any sign of krausen after pitching yeast.

Please Note: For best results we Always recommend ordering an Ice Pack with your liquid yeast. Ice Packs can be found below in the "You might Also Need" section.

This is my first pils. I usually make a starter but ran out of time and didn’t read that you have to pitch more yeast if starting cold. I pitched around 50° put it in the keezer at 48° and waited 24 hours. Nothing happened so I went online and saw I probably needed more yeast. I pulled the carboy out of the keezer and let it sit at room temp, around 55° while I was at work. When I came home it had taken off so I put it back in at 48° and it is going strong. It’s been about 10 days and still going so I can’t comment on how it finishes but it worked great starting with just one vile.

I have used this every winter for several years to make pilsner lagers. If you take your time, you get a great result. I used this yeast for 35 gallons of pilsner lager this past year, obtaining a very close clone to Pilsner Urquell. Love it, this makes me look forward to winter's approach.
